Ingredients You’ll Need

The magic of Key Lime Cheesecake lies in its simple, accessible ingredients—each one working hard to create that classic creamy texture and brilliant citrus flavor. Your pantry and fridge probably already contain most of what you’ll need, and those little extras like lime zest bring a pop of color and aroma that truly set this dessert apart.

Graham cracker crumbs: These create the cookie-like base that adds a satisfying crunch and subtle sweetness beneath the creamy filling.
Granulated sugar: Used in both the crust and the filling, it sweetens and balances the tangy lime flavor beautifully.
Unsalted butter (melted): Binds the crust together, giving it richness and helping it bake up perfectly golden.
Cream cheese (softened): The star of the cheesecake, providing that signature silky texture and creamy body.
Eggs: Essential for setting the cheesecake, giving it structure while keeping things lusciously smooth.
Sour cream: Adds a subtle tang and extra creaminess that complements the key lime’s brightness.
Key lime juice (fresh or bottled): Infuses the cheesecake with its distinct tropical, tart punch—fresh is best if you can get it!
Key lime zest: Elevates the citrus notes and adds flecks of gorgeous green throughout the filling and as a garnish.
Vanilla extract: Boosts the overall flavor and rounds out the sharpness of the citrus.
Whipped cream (optional): Perfect for swooping over the top for extra indulgence and balance.
Extra lime zest or thin lime slices (for garnish): These transform your cheesecake into a showstopper, adding color and an extra citrusy scent.

How to Make Key Lime Cheesecake

Step 1: Prepare the Crust

Start by preheating your oven to 325°F and greasing a 9-inch springform pan—this step is essential for easy removal later. In a medium bowl, combine the graham cracker crumbs, granulated sugar, and melted butter. Mix until everything’s evenly moistened, then press the mixture firmly and evenly into the bottom of your prepared pan. This solid, slightly sweet crust sets the stage for the creamy filling. Bake for 8 to 10 minutes until just golden and fragrant, then set aside to cool.

Step 2: Make the Filling

In a large mixing bowl, beat the softened cream cheese until it’s completely smooth and creamy—take your time here, as lumps at this stage will linger. Add the cup of sugar and keep beating until everything is beautifully combined. Next, add the eggs one at a time, mixing gently after each addition to keep the batter light and airy. Fold in the sour cream, key lime juice, lime zest, and vanilla extract. Beat again until the filling is silky smooth and pale, perfumed with that unmistakable lime fragrance.

Step 3: Assemble and Bake

Pour the luscious filling over your cooled graham cracker crust, smoothing out the top with a spatula for an even finish. Place the springform pan into the oven and bake for 55 to 65 minutes. You’re looking for the center to be just set and have a slight jiggle when the pan is gently nudged. Overbaking can lead to cracks, so keep a close eye during the last ten minutes or so.

Step 4: Cool Gradually

Turn off the oven and crack the door open, allowing the cheesecake to cool gently in the residual heat for one hour. This slow cooling process is the secret to avoiding cracks while locking in creaminess. Afterward, transfer the cheesecake to the fridge and chill for at least four hours, or overnight if you can wait—the texture only gets better with time.

Step 5: Add Toppings

Right before serving, top your Key Lime Cheesecake with billows of whipped cream and sprinkle over some fresh lime zest or artfully arranged lime slices. Not only does it look stunning, but it also layers more fresh flavor onto every slice.

How to Serve Key Lime Cheesecake

Garnishes

For the finishing touch, be generous with the toppings! A crown of freshly whipped cream and flecks of grated key lime zest gives your Key Lime Cheesecake both flair and fragrance. If you want to take it up a notch, arrange thin slices or twists of lime in a spiral across the top—it instantly transforms every slice into a celebration. Toasted coconut, a drizzle of berry sauce, or even delicate white chocolate curls also make elegant options that complement the tangy filling.

Side Dishes

With its bright citrus notes, this cheesecake pairs beautifully with lighter accompaniments. Try serving each slice alongside a simple berry salad, offering a refreshing contrast in color and flavor, or a glass of iced herbal tea or bubbly prosecco for a chic touch. If you want a classic pairing, a strong cup of fresh coffee after dessert never fails to delight.

Creative Ways to Present

Get playful with how you present your Key Lime Cheesecake! For a party, try slicing it into bars for easier serving, or use small mason jars or parfait glasses for adorable, individual portions. You can even swirl some puree from fresh raspberries or blackberries on top before baking for a gorgeous visual and flavor twist. Mini cheesecakes baked in muffin tins are a fun, portable option for potlucks or picnics, keeping all the flavor with less mess.

Make Ahead and Storage

Storing Leftovers

If you have any leftovers (lucky you!), simply cover the cheesecake tightly with plastic wrap or place slices in an airtight container. Stored this way, Key Lime Cheesecake will stay irresistibly fresh and creamy in the refrigerator for up to five days. The citrus flavor actually intensifies a bit as it sits, making your next-day slice even more delectable.

Freezing

Key Lime Cheesecake freezes beautifully, making it a fantastic make-ahead dessert. Once fully cooled, wrap the whole cheesecake or individual slices tightly in plastic wrap, followed by a layer of aluminum foil. Store for up to two months, and when ready to enjoy, thaw overnight in the refrigerator. The texture and flavor hold up so well, you’d never guess it wasn’t freshly made.

Reheating

This dessert is best enjoyed cold or at cool room temperature, so there’s no need to reheat. Simply let the cheesecake sit out for 15 to 20 minutes to take off the chill before serving. If you find the crust a bit firm from the fridge, that short rest will soften it just the right amount for dreamy, creamy slices.

FAQs

Can I use regular limes instead of key limes?

Absolutely! While key limes have a distinct floral tartness, regular (Persian) limes work wonderfully in a pinch. Just keep in mind the flavor will be slightly different, but still delicious and citrusy.

Why did my cheesecake crack?

Cracks can happen if the batter is overmixed or the cheesecake cools too quickly. Letting it cool gradually in the oven (with the door cracked) and avoiding overbeating the batter helps keep it beautifully smooth on top.

How do I know when my Key Lime Cheesecake is done baking?

The edges should look set while the center should jiggle slightly when you gently shake the pan. It continues to set as it cools, so avoid overbaking for the best texture.

Can I make this Key Lime Cheesecake gluten-free?

Yes! Simply substitute gluten-free graham crackers for the crust. The rest of the ingredients are naturally gluten-free, making it an easy swap for those with sensitivities.

Do I need a water bath to bake this cheesecake?

A water bath isn’t strictly necessary for this recipe—the gentle cooling instructions and proper mixing take care of most potential cracking issues. However, if you prefer extra insurance or extra creaminess, you can bake the cheesecake in a water bath for extra tenderness.

If you’re ready for a dessert that tastes like a vacation with every forkful, you simply have to try this Key Lime Cheesecake.
